Title: Improvements in or relating to keying of video signals
Inventor: ATTEW JAMES EDWARD
IPC: H04N9/75
Filed: 1985-09-19
Abstract: A keying apparatus for providing colour separation overlay of foreground and background video signals derives a keying signal by non-additive mixing from the foreground signal (4, 7), Keying means (9, 10, 11, 18, 19, 20) are controlled by the keying signal Bv and select between the foreground signal Rf, Gf, Bf and a combination of the background signal Rb, Gb, Bb and the luminance signal Y of the foreground signal. By making use of the foreground luminance signal to modulate the luminance of the background signal when the background colour portions of the video signal is being received, transparency and, optionally, shadow effects are obtained in a relatively simple circuit arrangement requiring little user adjustment for setting up video effects. Also, by making use of the foreground luminance signal to modulate the luminance of the background signal, relatively little noise is introduced into the background signal. <IMAGE>

Patent GB-2192860-A (GB)
Title: Dispensing carbonated beverages
Inventor: BETTERIDGE PAUL
IPC: G01F11/04
Filed: 1987-07-15
Abstract: Dispensing/metering apparatus comprises a cylinder (13) containing a reciprocatory piston (14). Outlet ducting (18,19,22) leads from the cylinder to a dispense station (24) which includes parallel pathways (25 and 26) controlled by valves (29 and 30) and leading to adjacent nozzles (27 and 28). One pathway (26) contains a constriction (31) which disturbs beer flowing through it and helps create a head on the dispensed beer. During the major part of its movement the piston dispenses undisturbed beer through the pathway (25) but when detected by an initial sensor (33 or 34) the beer is diverted through the pathway (26) and is dispensed in a more disturbed, frothy form. When the piston reaches a final sensor (32 or 35) the valves (29 and 30) at the dispense station close and the piston is brought to a halt by the beer ahead of it. Consequently there is no reduction in the pressure of the beer in the outlet ducting and bubble- formation is thus avoided. The speed of movement of the piston is reduced when disturbed beer is being dispensed, so that it approaches the final sensor slowly and the accuracy of the volume of the dispensed beer is thus increased. <IMAGE>

Title: Automatic sheet feed control systems for printers
Inventor: TSUKIHARA SATORU
IPC: G06K15/16
Filed: 1988-02-12
Abstract: In a printer having an automatic sheet feeder, the sequential feeding of sheets from a tray of the feeder to a printing position to print and then feed out the sheets is controlled so that a sheet is fed from the tray each time a sheet is to be discharged from the platen i.e. when a page feed or sheet discharge command is received, the sheet fed being stored on a support and fed therefrom to the platen when required for printing. A flag may be set when the sheet is fed to the support and reset when fed to the platen for printing. This prevents the sheet from standing for a long period around the platen and so acquiring a bend which creates problems when the sheet continues its passage through the printer.

Title: Fibre optic telemetry
Inventor: ATKINSON DR JOHN KARL
IPC: H04B10/50
Filed: 1988-03-17
Abstract: A method for converting an electrical signal to an optical signal in an optical fibre comprises applying the electrical signal to piezo-electric transducer in contact with the optical fibre so as to apply an acoustic wave to the fibre. Light passed through the acoustic wave in the optical fibre is modulated at the frequency of the electrical signal. In a network for monitoring the outputs from several sources (1,2...n), each source is connected to a common optical fibre communication channel by means of apparatus for implementing the above method. Each source is arranged to deliver its output signal to the channel as intermittent information packets. Each source is further controlled by means of a pseudo-random number generator such that the source delivers its output signal independently of the other sources at pseudo-randomly varying time intervals. <IMAGE>

Title: Vacuum pump for beverage container
Inventor: BEYER MICHAEL BRUCE
IPC: B67D1/10
Filed: 1989-02-21
Abstract: A resilient closure sleeve (106) is inserted into an opened beverage container and a pump located therein has a piston (36) reciprocated by hand in a cylinder (32) to evacuate air from the container. A sealing ring (56A), having a lip portion (72), is mounted on a reduced diameter portion (58) of the piston, and is movable along the length thereof. Displacement of the piston (36) in the cylinder (32) in direction A causes a pressure drop in chamber (54A) which in turn draws air past a check valve element (86) from the container. Displacement of the piston (36) in the opposite direction causes the sealing ring (56A) to move along the reduced diameter portion (58) of the piston, thereby opening an axial groove (68) and allowing air to pass from the chamber (54A) to an annular chamber (50A). The check valve element (86) has a resilient skirt (86A) which is forced against a conical seating by the pressure in the chamber (54A) to close off inlet passage (88). <IMAGE>
